The Tibetan Yogas of Dream and Sleep

The Tibetan tradition states that dreaming lucidly is not an end in itself, but it can be used as a context to engage in advanced and effective practices for liberation. Sleep yoga, also known as the yoga clear light, is a follow-up to dream yoga. This is an advanced practice that is similar to the most obscure Tibetan practices. It is a way to be aware in deep sleep, when the gross conceptual mind and operation of the senses cease.
